Clayton, MO (KSDK) - Kids who don't get enough sleep can get cranky, even have behavior problems and if it goes on long enough, develop some serious health risks.

Bedtime can be a constant battle. But here's something that might make you feel better: according to new research out of California, children in the United States do appear to be getting the recommended amount of sleep.

Dr. Joseph Ojile, CEO of the Clayton Sleep Institute, visits NewsChannel 5 to discuss the study and just how much sleep children should be getting each night.
